CULTIVATO R.

SPECIFICATION forming part of Letters Patent No. 319,609, dated dune 9, 1885.

Application filed March 10, 1885.

To aZZ whom it may concern.-

Be it known that I, JABEZ CURRY NELsoN, of Marion, in the county of Perry and State of Alabama, have invented a new and useful Improvement in Cultivators, of which the following is afull, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of one of my improved cultivators. Fig. 2 is a side elevation of the same. Fig. 3 is a front elevation of the same, partly in section, through the line as m, Fig. 2.

The object of this invention is to provide cultivators cohstructed in such a manner that they can be readily adjusted as the work to be done may require, and which shall be inexpensive in manufacture and effective in operation.

The invention relates to a cultivator constructed with atongue having rounded forward end and forked rear end, two arched bars attached to the said tongue, plow-beams secured adjustably to the arms of the arched bars, and bent standards having slotted cross'heads and securedto the saidbeams. The plow-standards are secured adjustably to the plow-beams by bolts and washers at their middle parts, and at their forward ends by bolts passing through the slots of their vertical cross-heads, whereby the said plow-standards will be firmly supported and can be readily adjusted. To the centers of the forward arched bar is attached a beam, to which is pivoted the center of a bar resting upon the forked tongue, and connected at its ends with the arms of the said forward arched bar by chains, into the links of which are hooked hooks connected with the whiffletrees, whereby the said whiftletrees will be supported, and the point of draft attachment can be readily adjusted higher or lower, as will be hereinafter fully described and then claimed.

A represents the tongue, the forward part of whichis made round, so that it can slidefreely in the ring 13 of the neck-yoke G, to allow the cultivator to be used with large or small horses and with long or shorttraces. The rear end of the tongue A is forked to give greater strength (No model.)

to the connection between the said tongue A and the arched bars D E, attached to it. The rear bar, D, is attached to the upper side of the rear end of the tongue A, and the bar E is attached to the lower side of the said tongue A at a little distance from the said rear end. F are the plow-beams, which are secured, by bolts G or other suitable means, to the lower sides of the horizontal arms of the rear bar, D, and to the upper sides of the horizontal arms of the forward bar, E. Several holes are formed in the arms of the bars D E to receive the fast ening-bolts G, so that the beams F can be readily adjusted at any desired distance apart.

H are the plowstandards, the rear parts of which are curved downward to bring them into proper position to receive the plow-plates. The standards H are secured at their middle parts to the opposite sides of the beams F by bolts I, and are held at such a distance from the said beams as will give the necessary lateral distance between the plow-plates of the standards of each beam by washers or blocks J placed upon the bolts I, between the said standards and the said beams. The inner standards, H, are placed at such a distance in advance of the outer standards as will give the necessary longitudinal distance between the plow-plates of the standards of each beam. The forward parts of the standardsH of each beam F are so bent that the forward ends of the said standards will rest squarely against the opposite sides of the said beam.

Upon the forward end of each standard H is formed a vertical cross-head, K, in which is formed a slot, L, curved upon the arc of a circle having its center in the axis of the bolt I, so that the said standards, by loosening the bolts M, passed through the slots L and the beams F, can be readily adjusted to give any desired pitch to the plow-plates.

To the rear ends of the beams Fareattached handles N, for convenience in raising the machine when turningit, and for guiding the machine when cultivating crooked rows of plants.

To the middle part of the bar E is secured a beam, 0, to which a fifth plow-standard can be attached when the machine is to be used for covering small grains.

To the forwardly-projecting end of the beam 0 is pivoted the center of the bar I, which attached to the arms of the forward arched bar, E. a

R are the whiffletrees, which are provided with hooks S to hook into the links of the chains Q, so that the said whiffletrees will be supported, and the point of draft attachment can be readily adjusted higher or lower, as may be desired.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- A cultivator constructed substantially as I 5 herein shown and described, and consisting of the tongue A, having rounded forward end and forked rear end, the two arched bars D E, attached to the said tongue, the plow-beams attached adjustably to the arms of the arched 20 bars, and the adjustable bent plow-standards having slotted cross-heads and secured to the said plow-beams, as set forth.
